Background Information Scientific Definitions: - 2 electrodes: anode(+) & cathode (-) - Electrolyte (carries charges) - Catalyst (speeds reaction) Fuel Cell Basics - needs a fuel to work - needs many cells
What is a Fuel Cell? Chemical reaction
generates voltage Unlike battery- no
recharge chemical reaction =
electrons flow→circuit; supply load with energy
How does it work? Hydrogen enters and
loses electron at anode
Proton →electrolyte, electron →circuit
O2 enters at cathode, O2 + p+ + e- = H2O
